The Batomon Showdown Supporter Pack is the only DLC listed on the base game's Steam store page. It carries its own Steam AppID 5255370, lists a $4.99 USD price on Steam, and is sold as a separate purchase alongside the base game. The Supporter Pack does not unlock the base Batomon Showdown release; players still need to buy the base game separately.

How the Supporter Pack relates to the base game
The Supporter Pack is positioned as optional DLC. Buying it does not grant access to Batomon Showdown itself, and not buying it does not lock any gameplay system behind a paywall. The base game ships with the asynchronous PvP auto-battler loop described on the store page, and the Supporter Pack exists separately as a way to support the developer on top of that core experience. If you only want to play Batomon Showdown, the base game purchase is enough. The Supporter Pack is a separate decision based on what the DLC listing offers.
